Hello, I use "complimentary purchase".
Its based on a-priori algorithm, so the evaluation couldnt use the same metrics as for
classification template engine. Unfortunatelly, pio provided only one tutorial so far:
https://predictionio.apache.org/evaluation/metricbuild/Can someone give me please an advice, how do I build evaluator in PIO for complimentary purchase?
Which metrics should I use? Thanks a lot!
